中继编译器语法错误：预期名称，找到“}”

Question

could not figure out why my query has syntax errors for hours. I copy and paste the query to graphiql and it works fine. When I ran relay compiler against my js, it threw this error. Does anyone have the same issue?

The weird thing is if I remove the "query HomeQuery", it gave different error to complain about operation name..

my code

import {graphql} from "react-relay";

const query = graphql`
    query HomeQuery {
        tasks {
            id
        }
    }
`;

my package.json

...
    "relay": "relay-compiler --schema ../resources/schema.graphql --src ./pages/test"
...

I ran npm run-script relay

the log
 relay-compiler --schema ../resources/schema.graphql --src ./pages/test


Writing js

turnout it is just your schema cannot have empty

type Mutation {

}

after I revmoed the empty type Mutation, everything is working....
